Re: [midgard-user] Internal links between pages ?

[David Schmitter]

Hi Marianne

I recently implemented GUID links to pages, if you use midgard from CVS 
you already have it. see attached documentation.

Hello,

If I'm in a page and I want to place an "internal" link to another page
somewhere else in the site structure... how do I do that?
If I use a full URL then if I move my page I have to replace the link
again. Any alternatives ?
Thanks,
Marianne

GUID links
**********

Make hypertext links that still work if the target is renamed or moved.

Installation
------------
Included in libmidgard + midgard-php4.

Link syntax
-----------
1. <A>

<a href="guid://ffffffffffffffffffffffffffffffff" other-attr="attr-value" ... 
>label</a>

if it is a page (has to be on the same host), gets rewritten to:
<a href="http://host/prefix/link/to/page"; other-attr="attr-value" ... >label</a>

if it is an attachment:
<a href="http://host/prefix/serveattachment/attachment-guid"; other-attr="attr-value" 
... >label</a>
(see Automatic attachment hosts)

if it is none of both:
empty string

2. <IMG>

<img src="guid://ffffffffffffffffffffffffffffffff[/image.jpg]" other-attr="attr-value" 
... >

gets rewritten to:
<img src="http://host/prefix/serveattachment/attachment-guid[/image.jpg]"; 
other-attr="attr-value" ... />

Function reference
------------------
New preparser function: 
mgd_ref(int mode, string guid, string attr, [string label])
where mode is 0: <A> link, 1: <IMG> link

Preparser enhancement
---------------------
<a href="guid://ffffffffffffffffffffffffffffffff" other-attr="attr-value" ... 
>label</a>
is recognized by the preparser and rewritten to
<?=mgd_ref(0, "ffffffffffffffffffffffffffffffff", 'other-attr="attr-value" ... ', 
'label')?>

This means it calls the mgd_ref function which then outputs the final, 
browser-readable form of the link.
